Abstract

High-entropy alloys (HEAs) contain five or more main elements, and each element ranges in content from 5% to 35%. Due to the abundant selectivity of elements, excellent structural stability, and adjustable active centers, HEAs have been widely used in electrocatalysis. Designing HEA catalysts at the atomic scale can deeply describe their structural complexity and accurately reflect the relationship between HEA structure and catalytic performance. In this Review, the atomic design of HEA-based electrocatalysts is introduced and it is evaluated in terms of activity, stability, selectivity, and efficiency. Ingenuity at the atomic level can customize the atomic composition and geometric structure of HEAs, thereby enhancing the intrinsic activity of the catalytic site, creating new active sites, and improving operational stability. The Review provides insights into excellent electrocatalytic properties and guidance for the design and synthesis of advanced HEA electrocatalysts from the viewpoint of atomic fabrication.

用于电催化的高熵合金的原子设计

高熵合金（HEAs）含有五种或五种以上的主要元素，每种元素的含量从 5% 到 35% 不等。由于高熵合金具有丰富的元素选择性、优异的结构稳定性和可调节的活性中心，因此被广泛应用于电催化领域。在原子尺度上设计 HEA 催化剂可以深入描述其结构的复杂性，准确反映 HEA 结构与催化性能之间的关系。本综述介绍了基于 HEA 的电催化剂的原子设计，并从活性、稳定性、选择性和效率等方面对其进行了评估。原子层面的独创性可以定制 HEA 的原子组成和几何结构，从而提高催化位点的内在活性，创造新的活性位点，并改善操作稳定性。本综述从原子制造的角度，深入探讨了 HEA 的优异电催化性能，并为设计和合成先进的 HEA 电催化剂提供了指导。
